Since you Rogue Mega Frolass is a Level 53 boss, you have to be at Level 53 or above if you want a fair fight. Once you’re at that level, you can then fight the boss and watch for the following attacks:  

  • Icy Wind: Rogue Mega Froslass sends a mini tornado towards you. Run to either side to avoid this. 
  • Shadow Ball: The boss summons a black orb and launches it at you. This attack is incredibly slow, so you can simply run to the side. 
  • Ice Pillars: The Pokemon will summon and drop large ice pillars from the sky. You have to keep moving to avoid this one. 
  • Blizzard: The boss summons an ice blizzard and attacks everything in the arena. You have to hide behind a block of ice to stay safe. 
  • Will-o-Wisp: Frosslass applies a burn status effect.
